She's not a regular on the club scene, but Taylor Swift looked like she was having a blast as she partied in Las Vegas on New Year's Eve.

Perhas it had something to do with her boyfriend Calvin Harris being on the decks, but the Blank Space beauty could not wipe the smile off her face as she threw shapes behind the DJ booth on Thursday night alongside Orange Is The New Black babe Ruby Rose.

The 26-year-old singer arrived at the club hand-in-hand with the Scottish hitmaker, but when he hit the decks had a party of her own.
